Start by gathering evidence: take clear photographs of the defect from multiple angles and document when the issue was first noticed. Review your original service agreement to understand the installer's liability and warranty terms regarding workmanship. Submit a formal written complaint to the company, requesting a site visit to assess the failure. If the installer is unresponsive, contact the manufacturer if the failure relates to product-specific installation requirements, as many warranties specify that improper installation voids future coverage.

If an installation error is identified post-completion, document the defects with high-resolution photos, timestamped logs, and written correspondence. Contact the original installer to request a formal inspection and review the installation contract for remedy clauses.
